To all whom it may concern:

Be it known that I, STEPHEN M.

This invention relates to door-latches; and it consists of the novelconstruction and combination of the parts hereinafter fully describedand claimed, whereby a bell is rung whenever the latch is operated.

O is the spring-bolt of the latch, and D is the operating-spindleof thelatch, which latter is a spring-operated latch of any approvedconstruction.

E is a bell secured to the door and provided with a hammer e. The hammerc has a spring-shank e, which'is secured to the spin dle D. F is an armwhich is secured to the spindle D.

G is a bracket which is secured to the door A, and g is a handle whichis pivoted to the bracket G by apin g. The handle 9 is movable in avertical plane, and his an arm which projects from the handle g andengages with a hole in the free end portion of the arm F.

H is the knob on the spindle D on the opposite side of the door from thehandle g.

When the handle 9 is operated to retract the bolt of the spring-latch,the hammer is raised, and when the handle g is let go the hammer strikesthe bell, so that attention is called to the fact that the door has beenopened.
